New Jersey Application .lune 29,

6 Claims.

This invention relates to a rolling colter for plows, and moreparticularly to a rolling colter adjustable transversely with respect tothe plow.

The main ob-ject of the invention is to provide a colter that is.adjustable transversely with respect to the plow, the transverseadjustment being made between the colter supports to align the colterand the plow.

Another object is to provide a bearing structure for supporting thecolter, said bearing structure being adjustable to compensate for wearin the parts thereof.

Another object is to provide means in the colter supports for carryingthe bearing structure thereon in iloating relation therewith.

Still another object is to provide a locking means on the colter supportfor maintaining the adjustment of the bearing structure and itscomponent parts.

These and other objects will be apparent from the following descriptionand drawing of the invention, in which:

Figure 1 is a vertical, sectional View through a colter disk andsupporting structure, embodying a. preferred form of the invention;

Figure 2 is an enlarged sectional View of the lower end of the coltersupport and a portion of the adjustable bearing member showing thefloating mounting of the samewith the lines A-A and B-B indicating rightand left floating limitations; and

Figure 3 is a side view showing a portion oi the colter support and thelocking means thereon, the view being taken along the line 3--3 ofFigure 1 and looking in the direction indicated.

Only those portions of a plow beam and the colter supports have beenshown as are necessary to describe the invention, the plow beam It)having securely attached thereto a secondary bracket member I I. Thecolter supports I2 are provided with holes I3 and are attached to thebeam l@ and bracket member H for vertical adjustment by bolts I4 andclips I5. The supports I2 are spaced apart .at their lower ends toDrovide space for carrying a colter disk I6. The disk It carries on eachside thereof a hub I i provided with `a conical extension I8.

At their lower ends each colter support is provided with a threadedopening le in axial alignment with the hubsV I I on the colter disk I6.Each supp-ort has cut out at the upper edge of each opening iii a keyslot 2U.

Adjustably threaded into each opening I9 is a bearing member 2l providedat its disk side with a conical bore 22 which ts over the conical 1936,Serial No. 87,875

extension i8 on each hub Il. Each bearing member 2i has cut therein akey-way 23 for a purpose to appear later.

When the bearing members ZI are threaded into the threaded openings I inthe supports 5 l2, they cooperate with the conical extensions i8 Von thehubs il to provide a bearing for the disk it, the disk and hubs beingrotatably journaled in the conical bores 22 in the bearing members 2i.When the correct transverse adjust.- ment of the disk with respect tothe plow has been attained and the bearing members 2i and conicalextensions it are fitted for correct bearing adjustment, the key slotsit in the supports l2 are aligned with the key-ways 23 in the bearingmembers 2l and keys 2d are inserted therebetween and held by pins 25inserted thro-ugh the keys 25 at the disk sides of the supports I2.

The key slo-ts 2t, the key-ways 23 and the keys 2d form a locking meansfor preventing rotation of the bearing members 2l.

The threaded openings i9 in the supports I2 are further machined tonarrow the sides of the threaded insides of the openings as at I9 toform a linear clearance between the threaded openings and the bearingmembers 2l, thus providing a slightly loose it between the supports l2and the bearing members 2l and allowing for .a floating movementtherebetween for self alignment of the colter disk. 30

The bearing members 2l are further provided with smaller bores 26, andthe hubs with co-rresponding bores 2'! in axial alignment with respectto an opening through the center of the colter disk I 6. A headed bolt28 extending through the openings and secured at its opposite end by anut 29 provides a spacing means between. the supports I2, preventing thesupports from spreading axially outward with respect to the disk. 40

It will be readily apparent that rotation of the bearing members EI willallow for transverse adjustment of the colter disk it, besides providingfor an adjustment in the entire bearing structure which may becomenecessary because of wear of the parts thereof.

It will be understood that only a preferred form of the invention hasbeen shown and described and that many modications of the same may beemployed without detracting from the 50 advantages obtained therefrom orwithout departing from the scope of the appended claims.

What is claimed is:

1. In a rolling colter construction, the combination of a colter disk, asupport at each side 55 thereof, a bearing member carried by eachsupport for axial adjustment therein, a hub on each side of the diskcooperating with each bearing member to form a bearing for the disk, anda locking means carried by each support and engaging each of the bearingmembers for preventing movement of the bearing members.

2. In a rolling colter construction, the combination of a colter disk, asupport at each side thereof, a bearing member carried by each supportfor axial adjustment therein, a hub on each side of the disk cooperatingwith each bearing member to form a bearing for the disk, a locking meanscarried by each support for preventing movement of the bearing members,and a spacing means extending through the disk, hubs, and the bearingmembers for preventing axial movement of the supports outwardly withrespect to the disk.

3. In a rolling colter construction, the combination of a colter disk; asupport at each side thereof; a bearing member adjustably threaded intoand extending through each support in axial alignment with the disk,each bearing member being provided with a conical bore; a hub on eachside cf the disk in axial alignment, said hubs being carried in theconical bores of the bearing members to provide a bearing for the disk;and a locking member carried between each support and each bearingmember for preventing rotation of the bearing member.

4. In a rolling colter construction, the combination of a colter disk;a, support at each side thereof; a bearing member adjustably and looselythreaded into and extending through each support in axial alignment withthe disk for slight movement relativ-e to the supports, each bearingmember being provided with a conical bore; a hub on each side of thedisk in axial alignment, said hub being carried in the conical bores ofthe bearing members to provide a bearing for the disk; a locking membercarried between each support and each bearing membeifor preventingrotation of the bearing member; and a bolt extending through the disk,hubs, and bearing members for preventing axial movement of the supportsoutwardly from the disk.

5. In a rolling colter construction, the combination of a colter disk, asupport at each side thereof provided with alined threaded openingstherethrough, a threaded bearing member threaded into each of saidopenings and extending axially through each of said supports, each ofsaid bearing members being provided with a conical bore, a. conical hubon each side of the colter disk cooperating with each bearing member toform a bearing for the disk, and a locking means removably carried byeach support and engaging each of the threaded bearing' members toprevent angular movement thereof.

G. In a rolling colter construction, the combination of a colter disk; asupport at each side thereof, each of said supports being provided witha threaded opening therein and each of said openings being provided witha key-slot; a threaded bearing member threaded into each of saidopenings, each of said bearing members being provided with a conicalbore and with a key-way axially in the threaded portion thereof, i

a conical hub on each side of the disk cooperating with each bearingmember to form a bearing for the disk, and a locking means between eachsupport and each bearing member for preventing movement of the bearingmembers, each of said locking means comprising a key removablypositicned between each of the aforesaid key-slots and each of theaforesaid key-Ways.
